Hello Everyone. [I just downloaded this tool ][1]called "C# version extended with break time by by Francesco Montors" As soon as i imported it onto my game i got the following error,
Assets/SplineController_CS_Extended/SplineInterpolator.cs(290,17): error CS0103: The name `DebugUtils' does not exist in the current context
